摘要:
在分析海滩失衡现状及总结人工养滩研究进展的基础上,提出在养滩设计过程中,应分析出现问题,根据地方需求并针对地形地貌条件制定方案。养滩设计最关键的是滩肩高度、剖面型式以及客沙粒径、坡度等参数的确定。滩肩补沙只是补充沙源的手段,而减缓侵蚀需要配合其他养滩方法,使养滩效果更佳。通过工程辅助手段,解决泥沙收支不平衡等问题,形成养滩补沙—构筑物护沙的综合养滩方法。在设计阶段应制定海滩监测计划,为海滩再养护参数确定提供数据。

Abstract:
In the process of beach nourishment project design, many problems should be considered, such as the needs of local government and the geomorphological background of the beach, as well as engineering requirements. In addition to some theoretical considerations, we discussed the methods and technical problems for design of a beach nourishment project in this paper. Critical parameters, such as the height of beach berm, profile of shoreface and grain size of nourishing sands, are considered, and engineering measures, such as headland control, beach nourishment, construction of offshore breakwaters and monitoring of beach profiles, are recommended.
